China UL Listed Riser Clamp Suppliers - Heavy-Duty Vertical Pipe Support from Trusted Factory for Fire Protection & Plumbing
Key Features & Benefits
Certified to meet UL 203 and MSS SP-58 standards, ensuring full compliance with NFPA 13, IPC, and local building codes for fire sprinkler and plumbing systems.
Made of high-strength carbon steel with electro-galvanized or hot-dip galvanized finish, offering excellent corrosion resistance for indoor and outdoor installations.
Two bolts evenly distribute clamping force, preventing pipe slippage even under full static load. The split design allows easy installation without disassembling the pipe.
Engineered to support the full weight of vertical pipe runs, eliminating the need for additional hangers at every floor level and reducing overall installation costs.
Fits standard steel, cast iron, and copper pipes (bare or insulated) in sizes from ½” to 8”, making it ideal for fire sprinkler risers, HVAC condensate lines, and plumbing stacks.
Installs directly on the pipe and transfers the load to structural supports or floor openings, streamlining multi-story piping installations.

Frequently Asked Questions (FAQ)
1. What is the primary function of a riser clamp?
A riser clamp is designed to support and anchor vertical pipe runs. It clamps tightly onto the pipe and transfers the load of the piping system to the building structure or floor penetrations, preventing vertical slippage.
2. Are these riser clamps UL and CUL Listed?
Yes, our riser clamps are fully UL and CUL Listed, meaning they meet the rigorous safety and performance standards required for fire sprinkler systems and general plumbing codes.
3. What pipe materials are these clamps compatible with?
They are compatible with standard steel, cast iron, and copper pipes. They can be used on bare pipes as well as insulated piping systems.
4. What sizes do you offer, and can I get custom sizes?
Our standard sizes range from ½” to 8”. We also provide custom engineering support and manufacturing for special sizes or unique load configurations to suit your project needs.
5. What type of corrosion protection do these clamps have?
They are manufactured from high-strength carbon steel and come standard with an electro-galvanized finish. Hot-dip galvanized finishes are also available for environments requiring higher corrosion resistance.
6. How long does shipping take for bulk orders?
Standard sizes typically have a fast lead time of 5–7 business days. Global shipping times vary depending on the destination, but we work closely with logistics partners to meet your construction timeline.
